STAIR-GARPET FASTENER.

Application filed July 20,

This invention relates to fasteners for stair carpets, and the main object is to provide means, substantially hidden from view, for effecting a transverse stretch to the carpet, so as to eliminate wrinkling, and for securing the carpet to the stair in such a way that it may very readily be attached and detached whenever it may so be desired. Other objects are also effected, and will be disclosed in the course of the following specification, reference being had to the accompanying drawing, in which:

Fig. 1 is a perspective view of a stairway section showing a carpet strip as secured thereto by my improved fastener.

Fig. 2 is an enlarged sectional detail view through a portion of the stair and rug.

Fig. 3 is a perspective detail section through a stair tread, as seen from the rear, and showing my improved fasteners as holding the carpet in place.

Fig. 4 is a perspective view pin clasps employed.

Figs. 5 and 6 are enlarged detail views of the clasp anchors showing them as in the same relative positions as they have when secured to the stair.

Referring to the drawing more specifically, and by reference characters, A designates the treads of a common stairway having the usual risers B. The carpet C follows the faces of the treads and risers, and must necessarily be fastened in the rear or inner corners formed by the treads and risers. The carpet fastening and stretching means may be described as follows:

Near each inner crease of the carpet, and upon the back thereof, I secure a pair of clasps 7 the carpet. These clasps, as shown in Figs. 4, 5, and 6, are of a form resembling ordinary safety pins, except that the back bar of each is coiled, as at 9, to receive or slip over a pair of anchor bars 10 and 11, having heads 12 and 18, respectively. The anchor heads 12 and 13 are inwardly opposed, with respect to each other, and are secured by screws 14 in the right angle formed by the tread and riser. The bars 10 and 11 are of smaller diameter than and are offset or eccentric with respect to the heads 12 and 13, so that when the heads are secured in place of one of the and 8, one near each side edge of pair 1926. Serial No. 123,745.

there will be sufficient clearance between the rods 10 and 11 and the treads and risers to permit the clasps T and 8 to slip onto said rods. The rod or bar 11 is considerably shorter than the corresponding member 10,

and the latter is provided with a compression spring 15, which tends to push the clasp 7 outwardly, thus giving a transverse stretch to the carpet.

The capet is attached in the following manner: After theclasps 7 and 8 have first been attached or pinned to the carpet, at the proper transversely opposed points, the loop 9 of the clasp 7 is slipped upon the bar 9. The carpet is then pulled in the other direction, against the tension of the spring 15, until. the loop 9 of the clasp 8 may be slipped over the end and uponthe bar 11. The slight retraction by the spring 15 will then center the carpet on the stair and at the same time keep it moderately stretched so as to overcome any tendency to wrinkle. To remove the carpet, for cleaning or other purposes, it is only necessary to reverse the above operation.

It is understood that suitable modifications may be made in the general design and structural details of the invention as herein shown and described, provided, however, that. said modifications come within the spirit and scope of the appended claims.

Having now therefore fully shown and described my invention, what I claim to :be new and desire to protect by Letters Patent is:

1. A device of the character described including a pair of anchor members adapted to be secured to a stair, and a pair of clasps adapted to be secured in a carpet and for engagement with said anchor members, one of said anchor members having a spring tending to spread the clasps apart.

2. A stair carpet fastener comprising a pair of anchor members secured to the stair and having outwardly disposed arms, and fastening members, carried by the carpet, for sliding engagement with said arms.

3. A stair carpetfastener comprising a of anchor members secured to the stair and having outwardly disposed arms, fastening members, carried by the carpet, for sliding engagement with said arms, and

and

a spring, carried by one of the anchor meinbers, tending to press the adjacent fastening member outwardly.

4. A carpet fastener comprising a pair of anchor members having outwardly disposed arms, a spring on one of said arms, and a pair of clasps adapted to be slidably carried by said arms.

5. A carpet fastener comprising a pair of anchor members having outwardly disposed 10 arms a spring on one of said arms, and a pair of clasps adapted to be slidably carried by said arms, said clasps having pin acting shanks for engagement with the carpet.

In testimony whereof I afiix my signature.
